When the 9-1-1 center got a call from someone across the country alerting them to a local fire, they were puzzled.

"My caller is actually in Indiana," declared Dispatcher #1.

At a fire station in another state came this reply. "Okay."

Dispatcher #1 continued. "My caller was playing online and someone posted that he was disabled and his stove was on fire and he couldn't get out."

Firefighters didn't brush it off as a prank. Instead they suited up, jumped in the truck and raced to the address where they found smoke pouring out of the windows.

"I was getting to the point where someone better come," said Bob Chambers, who suffers from Muscular Dystrophy and has limited movement. He was inside and home alone. When the fire started, he couldn't reach the phone, so he used his specialized keyboard to tap out a message to people he was playing a game with through Facebook.

"A couple of people that knew me shouted back 'Are you kidding?' I went no," exclaimed Chambers.

More and more cases of people posting cyber cries forhelpare popping up across the world.

A recent Red Cross survey found 44% of people would use social media to alert rescue crews if they couldn't call 9-1-1.

That's what Kwanza Hall did after he discovered an unconscious woman on the street. His phone battery was about to die, so he tweeted "PLEASE CALL THE PARAMEDICS" and gave his followers the location. An ambulance soon showed up and rushed the woman to the hospital.

"I'm just thankful she's alive," said Hall.

But experts warn that while both Bob and Kwanza were lucky, relying on social media in an emergency is risky.

"The public's expectation of what response they will get via use of social media is far beyond the capacity of public safety agencies to deliver on," explained a Fire Chief.

Most agencies do not monitor social media sites for people who need help. and if dispatchers are alerted to a post, they also have to figure out if it's a prank.

"It's always difficult to discern what may be real and what may not be real," said dispatcher #1.

If you do have a real emergency, is shooting a quick test to 9-1-1 an option?

Though the FCC is pushing for dispatch centers nationwide to update theirtechnologyto accept texts, right now it only works in a couple of places across the country.

Many cities and towns, like this one just can't afford it.

"Our resources are stretched to the limit," said this public safety expert, who pointed out that in the high-tech world we live in, dialing 9-1-1 is still the best way to contact emergency dispatchers.

That wasnt' an option in Bob's case, and his cyber pleas for help worked. He and his wife are thankful.

"I am so grateful that there was somebody out there that took it seriously."

If someone posted a request for help on a public safety agency's social media page and the department did not respond, could the agency be at risk for a lawsuit? Experts say that unless an agency claimed to accept emergency calls on their Twitter or Facebook page, probably not. But it's still an untested and up and coming area of the law.
